摘要：
A corn head row unit gearbox includes an input shaft, that rotates about afirst axis of rotationand that drives a set of bevel gears. The bevel gears transfer rotation of theinput shaft intorotation of a set of gathering chain output shafts about a second axis ofrotation, generallytransverse to the first axis of rotation. The gathering chain drive shaftseach rotate within abushing mounted within a frame structure of the gearbox. The frame structuredefines a borethat communicates with a bevel gear cavity, in which at least one of the setsof bevel gearsrotates, and an interior of the bushings mounted on the gathering chain driveshafts. Rotation ofthe bevel gears carries lubricant to an inlet aperture on the bore and drivesthe lubricant throughthe bore into the bushings.
